Many people believe that American biologist James Watson and English physicist Francis Crick discovered DNA in the 1950s. In reality, this is not the case. Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher.
Identification of DNA. DNA's discovery can be traced to 1868, when Swiss medical student Johann Friedrich Miescher began work on isolating proteins from white blood cells. Miescher found a substance that contained more phosphorus than cellular proteins and could not be broken down as proteins could. His discovery of what he called ânucleinâ proved an important key for scientists decades later who were trying to determine which chemical components of cells carried genetic information.
